| Abstract: | In an orthostatic challenge, Cambodian patients with orthostatic panic in the last month (OP patients) sometimes panicked
during orthostatic challenge, whereas those without orthostatic panic in the last month (NOP patients) did not. Also, OP patients
with primarily dizziness during orthostatic challenge panic (OPOCP-D) had a less vigorous physiological response than two other groups: (a) OP patients with primarily palpitations during orthostatic
challenge panic (OPOCP-P) and (b) NOP patients who had no symptoms during orthostatic challenge (NOPNOCP-NS). Among the patients experiencing orthostatic challenge–induced panic (i.e., the OPOCP-D and OPOCP-P patients), there were prominent orthostatic challenge–induced flashbacks and catastrophic cognitions, and the severity of
orthostatic challenge–induced flashbacks and catastrophic cognitions correlated with the severity of orthostatic panic in
the previous month and with the severity of orthostatic challenge–induced panic. |
